Description
Maximize the airflow and raw horsepower of your LS2 or LS3 engine with the Speed Engineering 2" Longtube Headers. Designed specifically for the 2008-2009 Pontiac G8 and the 2014-2017 Chevrolet SS Sedan, these headers provide a massive step up from restrictive factory manifolds.
While the common 1-7/8" headers are great for mild builds, these massive 2" primaries are the ultimate choice for high-horsepower applications, including cammed, stroked, or boosted setups. If you are looking to push your G8 or SS to its absolute limit, these are the headers you need.
Key Performance Features
Massive 2" Primary Tubes: Specifically engineered for maximum exhaust scavenging on high-output LS engines.
3" Collectors with Integrated Spikes: Directional collector spikes improve exhaust flow and reduce turbulence for consistent power delivery.
304 Natural Stainless Steel: Unlike cheaper 409 stainless or aluminized steel, 304 offers superior corrosion resistance and a lifetime of performance.
Dyno-Proven Gains: Expect a significant increase of 25+ RWHP depending on your supporting modifications and tune.
Precision Engineering: Features CNC machined flanges and TIG-welded mandrel-bent tubing for a leak-free, perfect-fit installation.
Applications:
2008-2009 Pontiac G8 (6.0L & 6.2L Engines)
